To w/wm it y H earn: ing from the condenser and the comparatively Be it known that I, FRANZ JOSEPH WEISS, a cold water in the tanks shall be brought to a citizen of the Republic of Switzerland, residmore or less average temperature before its ing in the city of Basle, canton of Basle, in return to the condenser; but While this is necthe Republic of Switzerland, have invented essary for the best results it is compatible 55 certain new and useful Improvements in Conwith a special mode of mixing, by which durdensers, of which the following is a true and ing the period of higher steam consumption exact description, reference being had to the the very hot water from the condenser is not accompanying drawings, which form a part immediately mixed with the colder water in thereof. the receiving-tanks and the supply for the 60 My invention relates to the construction of condenser during such period is much colder condenserssuch, for instance, as are used in than the average temperature of the contents connection with steam-enginesand has for of the tank, and a convenient device for efits object to equalize as far as possible the eififecting this mode of mixing is to arrange in cient operation of the condenser by equalizing the top of the tank to which the hot water 5 the vacuum when the steam consumption of is delivered one and preferably a series of the engine connected with the condenser is perforated plates, through the perforations variable. in which the water must pass to reach the I accomplish the above results by providing bottom of the tank, the supply for the con- 2 the condensers with water-tanks, the larger denser being drawn from said bottom.

Reference being now to the drawings in 5 The efficiency ofthe apparatusdepends upon which my invention is illustrated, Figure 1 is the fact that the temperature of the water a diagrammatic sectional elevation showing drawn from the tanks will always be lower I the application of my invention to a parallelthan the temperature of the water supplied to current condenser.

1n the drawings, Dis the supply-pipe for the cold condensing-water, which, as shown, has the portion extending into the condenserbody cl perforated, so that the water issues from the pipe in a series of jets. E is a water-intercepting receptacle placed in the condenser-body in position to intercept the water thrust out in jets from the pipe 1), which water of course has condensed a portion of the steam and become proportionately warmer. F is a pipe leading from the receptacle E to the tank, (indicated at G.) H is a pipe leading from the said tank to a distributing-receptacle I, which, as shown, is formed with a perforated bottom and sides, so that the water will issue therefrom into the lower part of the condenser in the form of jets. J J J &c., indicate a series of perforated partitions extending across the upper end of the tank i.

K, Fig. 4, indicates the wet-air pump, having a chamber K to receive the hot water and steam from the conduit (1. This connects through ports K with pump-chamber K and this chamber through ports K with the chamber K from which the air and steam escapes through passage K the water being run off through pipes K. K" is the pumpplunger.

In operation the steam entering through the pipe B is partly condensed by the water entering through the pipe D, which water, heated to a corresponding degree, is caught in the intercepting-receptacle E and delivered to the upper part of the tank Gr, mixing therein with the water already contained in said tank, which is at a temperature not greater than the average temperature to which the water is heated when it is caught in the interceptingreceptacle. Practically the water in the tank will under ordinary conditions be at a considerably lower temperature, because, 7111.250) (the, it is subjected to the cooling influence of the surrounding atmosphere. The water is drawn from the lower part of the tank G through the pipe H into the receptacle 1, from it issues again into the condenser, acting to further condense the steam, the hot water and airbeing finally drawn off through the conduit 0 and pump K. As shown, the receptacle 1 being situated below the receptacle E the flow of water from the tank into the receptacle 1 will be automatic and due simply to the head. Of course any extraneous means may be used, if desired, to effect the delivery of water from the tank Gr to the condenser-body; but the simple gravity automatic arrangement illustrated is eflicient and satisfactory.

It will be obvious that the use of my apparatus will materially increase the efliciency of the condenser when the supply of steam to be condensed is excessive or above the average, and it will be obvious also that where the supply of steam is materially below the average my apparatus may have temporarily the effect of increasing the pressure in the condenser. This, however, will only happen at times when the full efficiency of the condenser is not called for and will therefore not seriously interfere with the condensation.

It will be obvious that the water supplied to the tank Ur through the pipe F will necessarily pass through the perforations in the plates J J J &c., on its way downward to the bottom of the tank. When the water supplied to the tank is materially hotter than that already contained in it, the perforated plates will not tend materially to mix the hot and colder water together,and this is an advantage, because it insures a supply of comparatively cold water to the pipe H at the time when it is most necessary and efficient. On the other hand, when the water supplied to the tank is colder than that already contained in it the heavier cold water being broken up into jets by the perforated plates will sink more rapidly through and mix more rapidly with the hot water, so as to equalize the temperature of the tank and cool its lower portions, so that when the steam-su p ply increases the apparatus will be in the best attainable condition for effective condensation.

Any convenient mixing device may be used, it being understood that some means for equalizing the temperature of the water in the tank is always advantageous and should always be supplied.

A further excellent arrangement is shown in Fig. 3, where the tank G is connected with the pipe F leading from the condenser through pipe connections f &c., leading to various levels of the tank, while a pipe H leading back to the condenser, is connected to the tank by similar pipe connections if, also distributed at various levels. It will be obvious that in this arrangement the pipe H will be supplied with water having practically the average temperature of the water in the tank G Referring next to Fig. 2, which illustrates my invention as applied to a counter-current condenser, A indicates the body of such condenser; B, the steam-supply pipe; 0, the take-off pipe, which may be a barometric col umn, such as is familiar in connection with such condensers, or may be connected with a hot-water pump. C indicates the passage connected with an air-pump through which the air is drawn from the condenser. Such an air-pump is shown in Fig. 5 at L, consisting of a cylinder having a piston L entrance-ports L Z, with which pipe C connect, and exhaust-pipes L Z D indicates the cold-water-supply pipe, which, as shown,

1 cascade into connects with an annular chamber at, over the inner edge of which the water falls in a a receptacle d from the outer edges of which it again falls in a cascade into the annular intercepting-receptacle, (indicated at E,) from which the heated water passes through the pipe F to the tank G and thence through pipe H to the annular distributingohamber I, from which it falls in jets into the second annular intercepting-receptacle E, from which receptacle it passes by the pipe F to the tank Gr and thence through the pipe H to the distributing-receptacle 1 from which it falls in jets through the lower portion of the condenser-body and finally into the take-ofi pipe C.

The operation of this condenser so far as it presents any features of novelty is precisely as described in connection with Fig. 1 except that two tanks are employed, and obviously any convenient number may be used and material increase in efficiency gained by the multiplication.

Having now described my invention, What 1 claim as new, and desire to secure by Letters Patent, is
